' Application filed February 20, 1919. Serial No. 278,159.

To all to ham it may concern Be it known that I, CALVIN F. CHRISTO- PHER, a citizen of the United States, residing at Canton, in the county ofHaywood and State of North Carolina, have invented a new and useful Churn-Gearing, of which the following is a specification.

The device forming the subject matter of this application although capable of general use, is adapted to be employed in connection with a churn for transforming rotary motion 1 into right line reciprocation, and the invention aims to provide novel means whereby the result above mentioned may be brought about.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention; Fig. 2 is a top plan; Fig. 3 is a section taken on the line 3-3 of Fig. 1; Fig. 4 is a section taken on the line 44 of Fig. 1.

The device includes a base 1 carrying an inverted U-shaped frame 4 comprising a standard 100 provided with an outwardly extended arm 3. A stub shaft 5 is mounted in the frame 4 and thereon is journaled the sleeve 6 of a balance wheel 7 A gear wheel 8 is carried by the sleeve 6. A cap 6 is threaded on the outer end of the sleeve 6. A crank 6 is adjustable longitudinally in the cap 6' and is held therein by a set screw 6, the crank having a handle 6". A headed stub shaft 10 is mounted in the frame 4 and a disk 9 is journaled for rotation on the stub shaft, the head of the stub shaft being counter sunk into the disk, as clearly shown in Fig. 4. A pinion 8 is formed integrally with the disk 9 and meshes into the gear wheel 8.

The disk 9 is supplied with a diametrical groove 11 communicating with guide ways 101. A block or carriage 12 is mounted for adjustable reciprocation in the groove 11 j and is provided with ribs 102 received slidably in the guide ways 101. lug 14 projects from the disk 9 into the groove 11. A screw 13 is held for rotation but against longitudinal movement in the lug 14, the screw being threaded into the block or carriage 12. The screw 13 may be held against rotation by means of a set screw 15 threaded into the lug 14 and engaging the member 13. The

block or carriage 12 is provided with a crank pin 16, whereon is pivoted the lower end of a pitman 17 connected by means of pin 18" to a block or carriage 19 mounted to reciprocate 1 n.a yoke 20 projecting from a hub 25 constituting a part of a segment 26, the hub bemg mounted to rock on a pin 24 carried by the upper end of the standard 100. A screw 21 is mounted for rotation but is held against longitudinal movement in the yoke 20, the screw 21 being threaded into the block or carriage 19. The screw 21 is provided with a manipulating handle 22 and is held against rotation by a clamp screw 23- threaded into one end of the yoke 20.

The segment 26 meshes into a rack bar 27 held in place by a grooved wheel 28 journaled on a pin 29 mounted in the arm 3 of the standard 100. At'the lower end of the rack bar 27 there is a head 30 having an 0E- set socket 300 in which is received the upper end of the dasher rod 31 of a churn 2 mounted on the base 1, the rods 31 and 27 being held together, adjustably, by means of a set screw 32 threaded into the socket 300.

Rotation is imparted to the balance wheel 7 and to the gear wheel 8 by means of the crank 6", the gear wheel 8 operating the pinion 8 and motion being transmitted to the disk 9, the carriage 12 and the crank pin 16 operating the pitman 17, the pitman tilting the yoke 20 and the segment 26 with the pin 24 as a fulcrum, a right line reciprocation being imparted to the rod 27 and to the dasher rod 31. It will be obvious that the carriage 12 may be shifted by rotating the screw 13 and, in a similar way, the carriage 19 may be adjusted by rotating the screw 22. In this way, and by the manipulation of one or both of the instrumentalities above alluded to, the throw of the pitman 17 may be regulated.

Having thus described. the invention, what is claimed is In a device of the class described, a frame; a wheel j ournaled on the frame and having a peripheral groove; a lever fulcrumed on the frame and provided at one end with a segment, the lever having a yoke at its other end; a bar having a rack meshing into the segment, the bar being received slidably in the groove of the wheel, to hold the rack in mesh with the segment; a second wheel mounted to rotate on the frame and having a transverse groove; carriages slidable for adjustment in the yoke and in the groove of the second wheel; a pitman pivoted to the In testimony that I claim the-,fotegoing carriages; screws mounted in the yoke and as my own, Ihave hereto afiixed my signain the second Wheel for rotation and held ture in the presence of two witnesses. k therein against longitudinal movement, the CALVIN F.
